Vincent Audio has released the SA-31MK pre-amp and SP-331MK amp. Both are hybrid vacuum tube/solid-state gear.

All the info after the jump.

The SA-31MK is an upgrade from Vincent's SA-31. The output stage has two 6N16 vacuum tubes. The final output stage uses two more of the same tubes and functions in a pure Class A mode. The SA-31MK is analog only and features six RCA style inputs, and one record out.

The frequency response is a claimed 20 Hz to 50kHz +/- 0.5 dB.

Also announced is the SP-331MK amplifier. Up to 10 watts, the amp functions in a pure Class A mode. Above that, up to its claimed output of 150-watts per channel (8 ohms, 300 into 4), the 331MK functions in Class AB mode. Vincent claims this allows the SP-331MK to detail at low volumes while still being able to deliver high power when needed.

There are two SN16 tubes, along with a 12AU7 for the Class A power supply. As you can see in the image below, the caps and toroidal transformer are beefy, always a good thing. Frequency response is a claimed 10 Hz to 50 kHz +/- 0.5 dB and a THD of <0.1 % at 1 kHz at 1 watt.

Integra has released the DTA-70.1, a nine channel, THX Ultra2 Certified amp. Designed to allow the use of height or width channels, the 150-watt per channel amp packs a whopping 1,350 watts total. The 11.7-amp power supply has a big toroidal transformer behind the aluminum faceplate. Frequency response is a claimed 5 Hz to 100 kHz +/-3dB with a signal to noise ratio of 110 dB.
